Just in case you are wondering, there is nothing on any sign (even in the fine print) stating that you have to order by 5:30. So this heavily promoted late night meal ends 30 minutes early EVERY DAY, simply because the cook feels like cutting out early. 'The cook wants to clean up and get to his next job at 6.' They are basically going for the old school Vegas 'cheap meal while you gamble' model, and apparently it's been successful. Here is one of the signs within Harrah's:
There is a huge electronic sign on the front of Harvey's promoting this, as well. This is advertised throughout Harrah's and Harvey's, as well as various places in town. At 11pm, they start serving quick meals, including a 'full breakfast' (two eggs, meat, hash browns, toast) for $4.99, which is a great deal. Harrah's Lake Tahoe is heavily promoting the food service in the Highlander Bar on the 18th floor.
